R-R mount insert users chime in!
 

I had the front one in and was pleased with how little vibration there was, but took it out because I was worried about tearing the rear mount. Now I have a smooth idle, but the bucking is back! So, I just ordered the rear insert and will be trying both. It is my contention that with both front and rear the vibration will not be any worse than just the front and may even be less.

What have you guy/gals experienced?

I did the AWR front mount first (supposedly 88 durometer, bought "new" but second hand). Helped some, but more vibration. Then I did the AWR side inserts, just more vibration. Next was the RR rear inserts (cheaper and easier than AWR mount). Improved significantly, but shook like a dog passing a peach pit. Worse when I removed the side inserts. Then installed 70 durometer bushing in AWR front mount. Lowered vibration to bearable levels and the performance improved when I put the side inserts back in. Now that everything is broken-in, the axle hop is controlled and the vibration has moderated even more. Still a little rough at idle and a bit noisier overall, but acceptable.

I feel for you. What a trial!

Still doesn't help me, but thanks!

Bump. Anyone else? Roddimus?

are the R-R pretty easy to put in/take out? i heard that one of the AWR mounts was a pain and took a few hours. im guessing the R-R are also softer than the AWR mounts so that might be the kicker to go with R-R.

I have both RR-racing inserts. A first they were pretty ruff with lots of rattle. After they sets in, its only a little shake. There not bad at all.

Thanks for the input. :)
